Hello, is there a way to invalidate ListCollectionViewLayout after device rotation? It seems that when I use this layout and rotate my device, sizeForItem is not triggered in section controllers. It is working fine when switching back to UICollectionViewFlowLayout. Any advice would be appreciated. Thanks!

Hey @jurex !

You should be able to do this in your view controller. See Apple's UIViewController docs and look for the traitCollectionDidChange callback.

Thanks @jessesquires 👍

I've ended up with something like this:

override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
        super.traitCollectionDidChange(previousTraitCollection)
        adapter.reloadData(completion: nil)
}

It's not probably the most effective solution, but it's working. Thnx again for great library✌️
